A problem not least in the induction heating is the rapid heating and thereby resulting in the crucible temperature gradient. Here the ceramics quickly reach their limits. There are no problems in this respect with our standard material "LT".
The composition of the material and the special ceramic manufacturing technology results in crucibles with extremely good thermal shock resistance. The crucibles are usually provided with a special coating, which is baked with. The material is suitable for iron and stainless steel as well as for many non-ferrous metals and precious metals.
A special challenge for the crucible material is the inductive melting of platinum. Our KG-Z material ensures excellent multiple use even with larger amounts of melt.
For a slightly slower heating, our ZTA material is suitable, as the material shows no melting tendency even at temperatures in the area of the platinum melt.
Titanium melts are known to be very aggressive. In contact with titanium, Y2O3 has proven to be the most durable ceramic material. The high melting point above 2400 °C also makes Y2O3 interesting for use in the high temperature range.
In the area of titanium castings we also offer Y2O3 coated crucibles in addition to Y2O3 ceramics at. For inductive heating, these are made of a thermal shock resistant oxide ceramic.
In addition to the examples given, we can also offer crucible materials for the melting of other metals.
